Abstract
Recently, as the road network becomes complicated, it is often worthwhileto use the navigation system to search for the route from the present place to the destination. However, the existing navigation system not using actual image maps can easily lead to misrecognitions. This paper describes a method of virtual walkthrough image space construction, improving those problems, using plural omnidirectional images taken at each intersection and interpolating between two omnidirectional images of adjoining intersections effectively.
